What causes air masses? An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface. The Earth’s major air masses originate in polar or subtropical latitudes. What is the air mass classification […]
What is the volume of a 15 mm cube?
Which is appropriate for a helicopter approaching an airport for landing?
Which is appropriate for a helicopter approaching an airport for landing? If not otherwise authorized or directed by the tower, pilots of fixed-wing aircraft approaching to land must circle the airport to the left. Pilots approaching to land in a helicopter must avoid the flow of fixed-wing traffic. What is the minimum ceiling requirement for […]
How do you find the frequency of a wave on a graph?
What factors cause differential heating?
What factors cause differential heating? Differential heating The curvature of the Earth results in spreading out of solar energy towards the poles and a concentration near the equator. The curvature of the Earth results in solar energy having a larger amount of atmosphere to travel through to reach the Earth’s surface near the poles than […]
Which is the best example of heat being transferred mainly by radiation?
Which is the best example of heat being transferred mainly by radiation? Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of the Earth by the Sun. A less obvious example is thermal radiation from the human […]
What is the difference between halogen and noble gas?
What is the difference between halogen and noble gas? Halogens are Group 7 elements while noble gases are Group 0 elements. While some halogens, such as fluorine and chlorine are reactive chemical substances, all noble gases are inert, which means they do not react with other elements readily. This also explains why noble gases are […]
What are the 4 types of interstellar gas?
What are the 4 types of interstellar gas? In astronomy, the interstellar medium (ISM) is the matter and radiation that exist in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, as well as dust and cosmic rays. Is a large cloud of dust? A […]
What is it when a car speeds triples its kinetic energy?
What is it when a car speeds triples its kinetic energy? When a car’s speed doubles, what happens to its kinetic energy? When its speed triples? If a car’s speed doubles, its kinetic energy increases by 4, if its speed triples then the kinetic energy increases by 9. At what point in its trajectory does […]
What are the two main means of measuring personality?
What are the two main means of measuring personality? There are two basic types of personality tests: self-report inventories and projective tests: Self-report inventories involve having test-takers read questions and then rate how well the question or statement applies to them. Which of the following is not part of the five factor model of personality? […]
